Okay, so let's talk about something called verbs. Verbs are words that show action or a state of being. There are two types of verbs: regular and irregular verbs.
Regular verbs are like a toy robot that follows a pattern. They have a formula to become past tense. To make them past tense, you just have to add -ed to the end of the verb. For example, the verb "walk" becomes "walked" when we want to talk about something that happened in the past.
On the other hand, irregular verbs are like a big, scary monster hiding under your bed because they don't follow the same pattern as regular verbs. They need to be memorized individually to become past tense. For example, the verb "go" becomes "went" when we want to talk about something that happened in the past.
So, in summary, regular verbs are easy to figure out because we know the rules to turn them into past tense by adding -ed. Irregular verbs are a bit more difficult because we have to remember their individual past tense forms. But don't worry, with practice, we'll get the hang of it!
